Flood Insurance Rate Maps (FIRMs) for the City of Roseville were recently published on June 6'", 2010. Figure 15 displays the special flood hazard areas mapped by FEMA. 2.6.3 Groundwater Roseville is serviced by the St. Paul Regional Water Services (SPRWS) which supplies drinking water to the City of St. Paul and neighboring communities.
